Abstract
The invention comprises steroids of the formula <FORM:0938897/IV(a)/1> (wherein R is alkyl, alkenyl or alkynyl of at most 8 carbon atoms, chlorethynyl or 3-hydroxypropynyl) and their preparation by reacting the corresponding 17-ketone with the appropriate organometallic reagent containing the group R in an anhydrous organic solvent. Detailed examples are given, and reference is also made to the hydrogenation of products wherein R is alkenyl or alkynyl to give products wherein R is alkyl.
